The mouse problems seem worth investigating. Maybe dig in the junk drawer for a totally different kind of mouse (serial, bluetooth, usb-wired) and see if that changes anything.
Thanks John for your suggestion. I tried a different mouse and no joy... Marc....
Remind me again what kernel you are using, and what version of Vbox? I tend to purge my list mail fairly aggressivly. Hi John - I am running Leap 42.1 (x86_64) I am not running VBox, (which I think what you are referring to is VirtualBox?) Interesting that you should ask though because I am playing around with Docker. However, I don't think my system slowdowns has anything to do with Docker as these slowdown issues preceded my installation of Docker. And these slowdowns occur regardless of whether Docker is running or not. (The only reason I am fooling around with Docker, FYI, is so I can get the latest version of the Apache James email server up and running, something that OpenSuSE does not directly support.)
Marc....
So that was originally kernel 4.1. Are you still on that or have you upgraded?
It might be worth trying to boot with iomem=relaxed
added to the kernel command line.
It might not do anything but slowness has been detected in several distros as soon as kernel updates were applied due to tighter memory security.
Thanks John for the thought, I tried adding the iomem=relaxed option to the kernel options using the Yast Boot Loader tool, rebooted, and still no joy... In my fooling around with this issue, I have come across something that definitely triggers high CPU usage, and could be a clue. Although I cannot definitively say this is the smoking gun because I see high system CPU usage going on regardless of whether I do this or not - There is something very wrong going on when I use Dolphin to move stuff to the trash "Recycle Bin" (or sometimes it appears when I use Dolphin to simply move files from one location to another, i.e. drag and drop) and/or when I tell Dolphin to empty the trash. Doing so kicks off the 100% CPU usage and I hear the processor cooling fans kick into high speed. These tasks can take hours or even days to complete (if ever, some are still going on for over a week now. When I reboot the system, these tasks are not initially restarted, but if I do something like open the Recycle Bin to see if the files are still in it (after I told Dolphin to empty the trash) then these processes again kick off and the CPU usage goes up to 100%. The two (or more) spawned processes of interest are file.so and trash.so. However, unlike my original report and observations, these processes do report very high CPU usage also in the Process Table tab of KSystemGuard, top, atop, and htop so I am not 100% certain that this is related to the issue I reported - about something hidden is causing high CPU usage. Of interest also is doing file moves or deletes from the command line, i.e. using the mv, rm, and rmdir commands does not cause this high CPU usage to occur and those commands complete in a reasonable amount of time.
